Description

  The present invention relates to a pointer-type indicator device for a vehicle, and more particularly, to an indicator device for a vehicle having a pointer illumination function of guiding illumination light inside the pointer to illuminate the pointer itself.

  In a vehicular indicating instrument having a pointer illumination function, a pointer is attached at its base to a rotating shaft passing through an opening formed in alignment with a display plate and a light guide plate disposed on the back of the display plate. From the opening edge of the light guide plate, through the opening edge of the display plate on the light guide plate, light for illumination is radiated to the base, and when this irradiation light is guided to the pointer of the pointer, the pointer is moved. By shining, the visibility of the hands is enhanced and the decorativeness is enhanced.

  A cap for preventing leakage of irradiation light is attached to a base of the pointer to which the rotating shaft is connected. The cap is provided with a slit which is opened at the lower edge, and the cap covers the base of the pointer so that the pointer of the pointer passes through the slit, and the opening edge of the display plate through which the rotating shaft of the pointer passes. It is attached to cover the part.

  However, when light leaks from the gap between the lower edge of the cap and the display panel, the decorative effect is impaired by halation caused by the leaking light.

In order to prevent light leakage from between the cap and the display panel, it has been proposed to incorporate a light-blocking member such as a collar (for example, see Patent Document 1).
JP-A-2000-193497 (pages 3, 4; FIG. 1)

  However, when a component such as a light shielding member is incorporated, the number of components increases, which complicates the assembly process and increases the cost.

  SUMMARY OF THE INVENTION It is an object of the present invention to provide a vehicle indicating instrument with a pointer illumination function capable of preventing light leaking from between a cap and a display plate without increasing the number of parts.

  According to the present invention, basically, a projection that rises toward the cap is provided on the display plate itself of the vehicle indicator, and the projection forms a portion between the surface of the display plate on which the projection is provided and the lower edge of the cap. Prevents light leakage from between.

  Therefore, the invention according to claim 1 is a display panel having an opening, a base having a light-transmitting material, being disposed in the opening, being coupled to a driving rotary shaft through the opening, and A pointer having a pointer extending on the surface of the display panel and receiving light irradiation from the bottom side of the base; and a light-shielding member mounted on the base covering the base of the pointer and an opening edge of the display panel. In a vehicle indicator comprising a cap, the opening edge of the display panel is directed toward the lower edge of the cap to prevent leakage of irradiation light from between the surface of the display panel and the lower edge of the cap. The display device is characterized in that an annular protruding portion that stands up is formed integrally with the display plate.

  According to the first aspect of the present invention, the annular projection integrally formed on the display plate rises toward the lower edge of the cap, so that the conventional light shielding formed separately from the display plate on the display plate. Light leakage from between the cap and the display panel can be prevented without incorporating a member.

  Such projections can be formed relatively easily, for example, by drawing the display panel, and after forming the projections, the opening for the drive rotation shaft is formed using, for example, laser light. Can be formed.

  Further, even if the projection has a light-transmitting property, light transmitted through the projection is weakened by partial absorption by the projection, so that the visual influence of the leaked light is substantially reduced. Can be eliminated. In order to more reliably prevent light leakage, a light-shielding film can be formed on the projection by, for example, printing or painting.

  According to a second aspect of the present invention, in the first aspect of the present invention, the inner edge of the annular projection is formed in contact with a peripheral surface of the base so as to allow light to pass therethrough along the base. It is characterized by providing an interval between them. Since the irradiation light passes through the gap between the inner edge of the projection and the base of the pointer, the intensity of the light guided by the pointer is set to a desired value by considering the dimensions of the gap. Can be.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the protrusion is formed by a convex step surrounding the opening.

  Since the convex step can be easily formed by the above-described drawing or the like, the projection according to the present invention can be easily formed.

  According to a fourth aspect of the present invention, in the first or the second aspect of the present invention, the inner edge of the protrusion is located closer to the top of the cap than the lower edge of the cap in the cap. .

  Since the height position of the inner edge of the projection is located closer to the top of the cap than the lower edge of the cap, the lower edge of the cap and the top of the projection are arranged in an overlapping manner, so that leakage can be more reliably achieved. Light can be prevented.

  According to a fifth aspect of the present invention, in the first or second aspect of the present invention, the protrusion is formed by an annular folded portion surrounding the opening. Since the projection formed by such a folded portion functions as a reinforcement for the opening edge of the display panel, a reinforcement effect can also be expected.

  According to a sixth aspect of the present invention, in the first or second aspect of the present invention, the protrusion has an annular flat surface portion. This flat surface can be subjected to light control processing for reducing transmitted light, and the light control processing can set the intensity of light guided to the pointer to a desired value.

  According to a seventh aspect of the present invention, in the sixth aspect of the invention, the projection is subjected to a dimming process for reducing light transmitted through the projection. For this dimming process, for example, mesh printing can be performed on the surface of the protrusion. The intensity of the light illuminating the pointer through the protrusions can be changed in accordance with the degree of fineness of the mesh, so that the light guided to the pointer by the roughness of the mesh printing can be changed. Can be set to a desired value.

  According to an eighth aspect of the present invention, in the first aspect of the present invention, an irregular reflection preventing process for suppressing diffuse reflection is performed on an inner edge of the opening edge including the protrusion. By this irregular reflection prevention processing, irregular reflection due to irradiation light on the inner edge including the protrusion can be suppressed. Therefore, leakage to the display panel due to irregularly reflected light can be effectively suppressed, so that halation due to irregular reflection can be prevented, and thereby a reduction in the decorative effect due to halation can be reliably prevented.

  According to a ninth aspect of the present invention, in the invention of the eighth aspect, the irregular reflection prevention processing is performed by black printing applied to the inner edge. By this black printing, a black printing layer is formed on the inner edge. According to this black printing, a black printing layer for preventing diffuse reflection can be formed using a conventional printing process on a display panel, so that it is easy to add a special additional process to the working process. An effect of preventing diffuse reflection can be obtained.

  According to a tenth aspect, in the ninth aspect, the black print layer is formed on a surface of the display panel, and the black print layer is formed on a surface of the display panel. Thereby, it is possible to effectively reduce diffuse reflection toward the space between the display plate and the lower edge of the cap that covers the black print layer formed thereon.

  According to the present invention, since the annular projection integrally formed on the display plate rises toward the lower edge of the cap, a conventional light-blocking member formed separately from the display plate is incorporated into the display plate. In addition, light leakage from between the cap and the display panel can be prevented.

  Hereinafter, features of the present invention will be described in detail with reference to the illustrated embodiments.

<Embodiment 1>
FIG. 1 is an enlarged view of a main part of the present invention. Prior to description along FIG. 1, the entirety of a pointer type indicator for a vehicle according to the present invention will be schematically described along FIGS. 2 and 3. I do.

  The vehicle indicator 10 according to the present invention is a speedometer in the example shown in FIG. The vehicle indicator 10 includes a display panel 11 made of a transparent synthetic resin plate. On the display plate 11, a display portion 12 such as a character indicating a speed, a number indicating a speed value, and a scale thereof is formed of a translucent portion on a background color by multicolor printing of a conventionally well-known printing. Further, on the display plate 11, a pointer 14 with a cap 13 having a light-shielding property is arranged.

  Further, as shown in FIG. 3, the vehicle indicator 10 includes a housing 15 formed of, for example, a lower housing member 15a and an upper housing member 15b, each of which is made of a synthetic resin material. A well-known circuit board (not shown) is provided on the lower housing member 15a. On the circuit board, a movement 16 comprising, for example, a stepping motor and a light source 17 such as an incandescent lamp or a halogen lamp are provided. The portion is provided so as to be exposed from the housing 15. The movement 16 is arranged with its rotating shaft 16a facing an opening region 18 formed in the upper housing member 15b.

  The display panel 11 is disposed so as to cover the opening area 18 of the upper housing member 15b. The display plate 11 is provided with an opening 19 that allows the rotation shaft 16 a of the movement 16 and the pointer 14 to be connected. A well-known light guide plate 20 made of a transparent resin material is disposed on the back surface of the display plate 11, that is, on the surface located on the housing 15 side. The light guide plate 20 has an opening 21 that matches the opening 19 of the display plate 11.

  The pointer 14 is made of a translucent and colored synthetic resin material such as polycarbonate or acrylic. The pointer 14 has a base 22 on which a boss portion 22a is formed, and a pointer 23 projecting from one side of the base in a radial direction of the base. The boss portion 22a is disposed through the opening 19 of the display panel 11 and the opening 21 of the light guide plate 20, and receives the rotation shaft 16a of the movement 16 so that the boss portion 22a rotates integrally with the rotation shaft 16a. Connected to the shaft.

  A cap 13 which is open at one end is attached to the base 22 of the pointer 14 so as to allow insertion of the pointer 23 in a slit 13a which opens to the lower edge thereof. Thus, the cap 13 covers the base 22 of the pointer 14 and the edge of the opening 19 of the display panel 11. In addition, the pointer 23 extends from one side of the base 22 through the slit 13 a and extends on the display panel 11 so that the lower surface 23 a is parallel to the display panel 11.

  The pointer 14 is rotated integrally with the rotation shaft 16 a to indicate the display unit 12 on the display plate 11 in accordance with the operation of the movement 16.

  The light source 17 illuminates the display plate 11 from behind by passing through the light guide plate 20 so that the display unit 12 formed of a translucent portion on the display plate 11 rises from the background. The light from the light source 17 is guided to the base 22 of the pointer 14 through the light guide plate 20 to make the pointer 14 shine, as indicated by the broken line indicated by reference numeral 24 in FIG.

  As shown in an enlarged manner in FIG. 1, the edge of the opening 21 of the light guide plate 20 has a region corresponding to the rotation range of the pointer 23 of the pointer 14 from the light source 17 guided inside the light guide plate 20. A reflecting surface 20a for directing light toward the base 22 of the pointer 14 is formed. In addition, a reflection surface 22 b for reflecting the light 24 guided by the base toward the tip of the pointer 23 is formed on the base 22 of the pointer 14.

  As shown in FIG. 1, the display plate 11 is made of, for example, an uncolored transparent acrylic synthetic resin plate, and has a display layer 12 and a printing layer formed by multicolor printing for the background on the surface thereof. . With this printing layer, the edge of the opening 19 of the display panel 11 exhibits light-shielding properties. A projection 25 rising toward the cap 13 by, for example, drawing is formed on an edge portion of the display plate 11 that exhibits light shielding properties.

  The protruding portion 25 has a circular peripheral wall portion 25a that rises at a right angle from the display panel 11, and a top portion 25b that is continuous with the upper edge of the peripheral wall portion and that has a flat surface that projects inward at a right angle to the upper edge. At the center of the flat top 25b, the opening 19 is formed concentrically with the top by, for example, cutting using a laser beam. Thus, the projection 25 is formed around the opening 19.

  The height of the top 25b of the projection 25 is large enough that the top 25b provided on the upper edge is located above the lower edge of the cap 13, that is, on the cap top side. The edge of the opening 19, which is the inner edge of the projection 25, is spaced from the boss 22a of the pointer 14. Therefore, the light from the light guide plate 20 toward the reflection surface 22b of the display panel 11 is not blocked by the projection 25 of the display panel 11, and the lower edge of the cap 13 and the projection 25 are separated by the illumination light 24. , That is, in the axial direction of the boss portion 22a.

  The distance between the edge of the opening 19 and the boss 22a of the pointer 14 is determined by the path of light guided from the reflection surface 20a of the light guide plate 20 to the reflection surface 22b provided on the base 22 of the pointer 14, as described later. Therefore, the distance between the edge of the light amount opening 21 and the boss portion 22a of the pointer 14 is appropriately set so that an appropriate amount of light is guided from the light guide plate 20 into the pointer 14. In the example shown in FIG. 1, the aperture 19 of the display panel 11 has a larger diameter than the aperture 21 of the light guide plate 20. The caliber of the former can be made approximately equal to that of the latter.

  In the vehicular indicator 10 according to the present invention, the display unit 12 on the display plate 11 is clearly displayed so as to rise from the background of the display plate 11 by the lighting effect of the light source 17 in the housing 15. In the rotation range of the pointer 14 accompanying the operation of the movement 16, light 24 guided from the light source 17 via the light guide plate 20 is transmitted from the reflection surface 20 a of the light guide plate 20 through the opening 19 of the display panel 11 to the base 22 of the pointer 14. Will be guided to. The light 24 guided to the base 22 is guided from the reflection surface 22 b provided on the base 22 to the tip of the pointer 23. Therefore, as is well known in the related art, the entirety of the pointer 14 including the pointer 23 shines due to the scattering of light inside the pointer 14, so that the visibility of the pointer 23 is improved, and the vehicle indicator is used. 10 decorativeness is enhanced.

  In the indicator 10 for a vehicle, a part of the light 24 directed to the base 22 of the pointer 14 through the opening 19 of the display panel 11 by the reflection surface 20a of the light guide plate 20 is, for example, similar to the conventional one. Diffuse reflection occurs on the lower surface 22c. A part of the diffusely reflected light is directed between the lower edge of the cap 13 and the surface of the display panel 11 or the gap below the pointer 23 of the slit 13a. The annular protruding portion 25 rising inside prevents the irregularly reflected light from reaching the gap between the cap 13 and the display panel 11.

  Accordingly, irregularly reflected light can be reliably blocked without incorporating a separate member into the display panel 11 as in the related art, and this diffused reflected light can be prevented from leaking out of the gap between the cap 13 and the display panel 11.

  The projection 25 has been described with respect to an example showing light-shielding properties. However, the projection 25 is formed of a transparent or translucent resin material without printing on the peripheral wall 25a and the top 25b constituting the projection. can do. In this case, the above-mentioned irregularly reflected light passes through the projection 25, and a part of the energy is absorbed by the peripheral wall 25a by this transmission, so that it is possible to prevent the generation of the strong leak light as in the related art. In order to more reliably prevent the leakage light, it is desirable that at least the peripheral wall portion 25a or the above-described peripheral wall portion 25a and the top portion 25b be provided with a light-shielding property by printing or painting.

  As shown in FIG. 1, irregular reflection occurs on the inner edge including the protrusion 25 formed at the edge of the opening 19, that is, in the annular region R including the peripheral wall 25a and the top 25b in the first embodiment shown in FIG. A black print layer for preventing the occurrence of black can be formed.

  This black print layer can be formed simultaneously in a printing step for obtaining the display portion 12 of the display panel 11. The above-mentioned black print layer can be formed on the surface of the display panel 11 facing the cap 13, and the anti-reflection treatment for forming the black print layer allows the irradiation light at the inner edges 25 a and 25 b including the protrusion 25 to be formed. Diffused reflection due to light can be suppressed. Therefore, leakage to the display panel 11 due to irregularly reflected light can be effectively suppressed, so that halation due to irregular reflection can be prevented, and thus, a reduction in the decorative effect due to halation can be reliably prevented.

  As the irregular reflection prevention processing, various processing methods such as chemical processing or laser irradiation can be adopted instead of the above-described printing means. Further, the black print layer can be formed on the back surface of the display panel 11.

  However, as described above, the irregular reflection preventing black printing layer is formed by printing on the inner edges 25a and 25b of the surface of the display panel 11, thereby preventing the diffuse reflection using the conventional printing process on the display panel 11. Therefore, the diffused reflection preventing effect can be easily obtained without adding a special additional step to the working process. In addition, the black printed layer formed on the surface of the display panel 11 effectively reduces diffuse reflection between the display panel 11 and the lower edge of the cap 13 that covers the black printed layer formed thereon. Therefore, the leakage light due to the irregular reflection can be effectively reduced.

<Embodiment 2>
As shown in FIG. 4, in the vehicle indicator 110 according to the second embodiment, a projection formed around the opening 19 of the display panel 11 is formed by an annular folded portion 26 rising toward the cap 13. I have. A flat surface 27 is formed on the inner edge of the annular folded portion 26, and the opening 19 is formed on the flat surface 27.

  In the example shown in FIG. 4, the folded portion 26 has its top located below the lower edge of the cap 13. However, the folded portion 26 is arranged radially outward from the opening 19 by the flat surface 27 that is the inner edge thereof, and as a result, is arranged close to the peripheral wall of the cap 13. The emission of the above-mentioned irregular reflection from between the lower edge of the cap 13 and the surface of the display panel 11 can be reliably prevented.

  In addition, the folded portion 26 functions as a reinforcing rib because the double wall portion serves to reinforce the opening 19 of the display panel 11, thereby increasing the strength at the edge of the opening 19 of the display panel 11. .

  In the second embodiment, as shown in FIG. 4, a black print layer similar to that described in the first embodiment can be formed in the annular region R including the folded portion 26 and the flat surface 27. Emission of irregularly reflected light can be effectively suppressed.

<Embodiment 3>
In the vehicle indicator 120 according to the third embodiment shown in FIG. 5, the projection 28 formed around the opening 19 of the display panel 11 has the same peripheral wall 28a and the same peripheral wall as the first embodiment. It consists of a right-angled top 28b. The height dimension of the peripheral wall portion 28a has a value smaller than the distance from the surface of the display panel 11 to the lower edge of the cap 13. Therefore, the top portion 28 b is located below the lower edge of the cap 13. However, the outer diameter of the flat annular top portion 28 b is large enough to allow the peripheral wall portion 28 a to approach the peripheral wall of the cap 13. Therefore, as described in the second embodiment, the projection 28 reliably prevents the emission of the above-mentioned irregular reflection from between the lower edge of the cap 13 and the surface of the display panel 11.

  The flat top portion 28b can be subjected to a dimming process such as mesh printing. The amount of light transmitted from the reflection surface 20a of the light guide plate 20 to the reflection surface 22b provided on the base 22 of the pointer 14 from the reflection surface 20a of the projection 28 depends on the roughness of the printed mesh pattern. Increase or decrease. Therefore, by forming an appropriate mesh pattern by the mesh printing, the amount of light transmitted through the top portion 28b of the projection 28 and guided into the hands 14 can be set appropriately.

  In the third embodiment, as shown in FIG. 5, regardless of the presence or absence of the dimming process, the annular region R including the protrusion 28 having the peripheral wall 28a and the top 28b is provided in the first embodiment. A black print layer similar to that described above can be formed, whereby emission of irregularly reflected light can be more effectively suppressed.

<Embodiment 4>
In the third embodiment, the top 28b has the projection 28 perpendicular to the peripheral wall 28a. However, in the vehicle indicator 130 shown in FIG. 29b is formed so as to be inclined from the outside toward the inside of the opening 19 in the direction away from the cap 13. The inclined flat top 29b directs irregularly reflected light 22c from the lower surface 22c facing the top to the reflection surface 22b. Thereby, the irradiation light from the light guide plate 20 can be effectively guided into the pointer 14.

  This flat top 29b can be provided with the same dimming means as the top 28b of the indicator 120 for a vehicle.

  The annular projection formed around the opening 19 of the display panel 11 can be formed in a desired cross-sectional shape as appropriate, regardless of the above-described example.

  Further, in the fourth embodiment, as shown in FIG. 6, regardless of the presence or absence of the dimming process, the annular region R formed by the protrusion 29 having the peripheral wall portion 29a and the top portion 29b is formed. A black print layer similar to that described in 1 can be formed, whereby emission of irregularly reflected light can be effectively suppressed.

  According to the first aspect of the present invention, since the annular projection that rises toward the lower edge of the cap attached to the pointer is formed integrally with the display plate, it is formed separately from the display plate. It is possible to prevent light leaking from between the cap and the display panel without incorporating the conventional light shielding member. Therefore, it is possible to prevent light leakage without increasing the number of parts and complicating the assembling process as in the related art, and suppressing an increase in cost.

  According to the second aspect of the present invention, by taking into account the size of the gap between the inner edge of the annular projection formed on the display panel and the base of the pointer, the intensity of light guided by the pointer can be set to a desired value. Can be set to a value.

  According to the third aspect of the present invention, by forming the annular projection surrounding the opening of the display panel as a convex step, the convex step can be easily formed by drawing or the like. The protrusion according to the present invention can be easily formed.

  According to the fourth aspect of the present invention, the lower edge of the cap attached to the pointer and the top of the projection formed on the display panel are arranged in an overlapping manner, so that the lower edge of the cap and the top of the projection are arranged. Light can be prevented more reliably.

  According to the fifth aspect of the present invention, the annular projection surrounding the opening of the display panel is formed by a folded portion, so that the projection can function as a reinforcing portion. The part can be reinforced.

  According to the invention described in claims 6 and 7, an annular flat surface portion is provided on the projection, and the flat surface can be subjected to dimming processing for reducing transmitted light. The intensity of the light guided by the pointer can be set to a desired value.
